METHOD OF DEVELOPMENT AND DEVICE FOR TWO-CHANNEL COLLIMATOR SYSTEMS WITH INDICATOR ON COMMON OPTICAL AXIS Russian patent published in 2015 - IPC G02B27/01 G02B27/30 G02B27/34 F41G1/30 

FIELD: physics.

SUBSTANCE: claimed method comprises fitting of lens and two indicators on optical axis, one of said indicators making a transmission type. Image splitter filter composed of parallel-sided plate is fitted between said indicators. Light-diffusing marks are applied on second transmission indicator surface, on its second wavelength, at the lens front focal plane, to reflect the radiation from second wavelength to said splitter filter. The latter reflects radiation of second wavelength from second indicator and transmits radiation of first wavelength of first indicator towards objective lens.

EFFECT: higher capacity and reliability of data output owing to combination of two channels of independent data Simplified design, decreased weight and overall dimensions.
